What are the factors involved in the selection of industrial aluminum profiles?
Corrosion resistance: corrosion resistance, including chemical corrosion, stress corrosion resistance and other properties. In general, the corrosion resistance of 1 pure aluminum was the best, and the 5 lines showed good performance, followed by the 3 and 6 lines, and the 2 and 7 lines were poor. The selection principle of corrosion resistance should be based on the occasion of its use. Corrosion resistant materials used in high strength alloys must be made of a variety of corrosion protection composites.
Hardness: many customers are very concerned about the purchase of aluminum, and the preferred hardness is directly related to the chemical composition of the alloy. Secondly, the different states also have great influence. From the highest hardness, 7 lines, 2 lines, 4 lines, 6 lines, 5 lines, 3 lines, 1 lines are reduced in turn.Strength: strength is an important factor that must be taken into consideration when designing a product. As an aluminum alloy component, the appropriate alloy shall be selected according to the pressure to be taken. The strength of pure aluminum is the lowest, while the 2 and 7 series heat treatment alloys have the highest degree, and the hardness and strength have a certain lower phase relationship.
Machinability: processability, package, formability, and machinability. Because of the formability and the state, in the selection of aluminum alloy brand, but also need to consider the range of various state of strength, usually the high strength of the material is difficult to shape. The platform should be bent, stretched, deep washed and so on. After finishing, the material has the best formability. On the contrary, the material in the heat treatment state has the worst formability. The cutting of the poor, Aluminum Alloy for molds, machinery parts need cutting better, on the other hand, the low strength of cutting is poor, the mold, machinery parts and other products need cutting, cutting Aluminum Alloy are important factors to consider.Weldability: the weldability of most aluminum alloys is no problem, especially Part 5 series aluminum alloy. It is specially designed for welding consideration. Relatively speaking, it is difficult to weld parts of the 2 and 7 series aluminum alloy.Decorative performance: aluminum used in decoration or some special occasions, need the anodic oxidation of the surface coating processing, to obtain the corresponding color and surface tissue, then the decoration should be a key consideration, in general, good corrosion resistance of the anode material, processing performance, surface treatment coating performance. The performance is very good.
